IP Addressing – IPV4 Essential Concepts and Advanced Subnetting Explained using Subnetting Question

IPv4 IP addressing is fundamental to network communication, enabling devices to identify and communicate with each other. An IPv4 address consists of 32 bits, typically written in decimal format as four octets separated by periods (e.g., 192.168.1.1). This addressing scheme supports around 4.3 billion unique addresses. IPv4 addresses are divided into classes (A, B, C, D, and E) and include special ranges for private networks and reserved purposes. Understanding IPv4 addressing is essential for configuring and managing network devices and ensuring proper data routing.
